SEALING ASSEMBLY FOR INFLATABLE IN-EAR DEVICE

摘要

An inflatable in-ear device (1 ) includes a core member (2) with a platform (12) provided with a sealing assembly in the form of a locating recess (20) for the registration of a retention ring (34) formed around a defining opening of a sheath (32) arranged in close circumjacent manner around the platform (12) attached to the core member (2), an abutment surface (20') being formed on a capping (22) for the platform (12) and the core member (2) whereby in use positive location of the retention ring (34) within the recess (20) is achieved by the closure of the recess (20) by the abutment surface (20'). A space (50) is defined between the sheath (32) and the core member (2) for the injection of a settable material used for the inflation of the sheath (32) once the device (1) is emplaced within the ear canal (4) of the ear.
